Try running it with a specific exchange, see if that narrows down the error:

coinx price btc -e kraken

etc

[gitGksgk]

the same error appears again..

I don't know if it's relevant, but i have just configured api key only on kraken. Yet none of the five exchange returns true result. Moreover, specifying -e parameter doesn't make any difference on the outcome of other coins whose value are correctly returned. Here's the complete log and thank you for your time.

I've tried ETH and it often takes a long time (say 10 hours) before returning value (which i've never seen). Currently BTC and ETH are the only known coins that coinx on my machine cannot reach the prices.
